index_product · Search MCP: Risk & Policy

WHAT IT DOES

What index_product does on Search MCP

AI agents use index_product to create or update resources in Search MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Search MCP environment.

WHY IT NEEDS A POLICY

Why index_product needs a policy

Indexing a product in Elasticsearch creates or updates a document in the index, which is a write operation. The name strongly suggests adding or updating product data. However, since the description is empty, confidence is reduced.

From the tool's definition Tool name 'index_product' implies writing/indexing a product document into Elasticsearch. Description is empty and uninformative.

index_product Rate-limited

index_product stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
